I am not implying that the iPad Pro can replace the MacBook Pro. They are two different animals, though there is clearly some overlap in capability. It’s just encouraging to know that the iPad Pro development has brought it up to laptop level performance.

The tablet vs laptop overlap has arrived. There’s not going to be a one-size-fits-all answer, but after iOS 11, the iPad Pro vs Macbook consideration will not be for early adopters anymore.
